Animated glowing textures - how?
You can use curves, give them some extrusion and an emissive material. Then animate the bevel start and end factors, like in these links:

How to make an object appear/visible along a path
The main problem you will face is that you need to separate the curves created by OpenStreetMap or create new ones. OSM creates multiple segments on a single curve object and that would not work for animating Bevels.
